Signs wired to trigger lawn sprinklers, strobe lights, a loud siren and videocam would be kinda fun, too.

“Signs wired to trigger lawn sprinklers, strobe lights, a loud siren and videocam would be kinda fun, too.”

As long as it was also wire to 240 volts. (Especially getting a video of the reaction).

I know that setting up a shotgun at the front door and tied to the door is illegal - in case a fireman or cop needs to enter the home to help someone. I wonder if the same applies to a yard sign.
